mcp-servers

The Python server uses FastAPI and Pydantic for robust request handling and validation, structured logging with Loguru, and Prometheus metrics. No direct use of `eval`, external command execution with unsanitized input, or hardcoded sensitive credentials within the server's source code (`mcp_server.py`). The default CORS `ALLOWED_ORIGINS` is set to `*` which allows requests from any origin, making it broadly accessible; this should be restricted in a production environment, although it is configurable via environment variables. The current database interaction methods (list_tables, discover_data, prepare_query, query) are mocked within the provided Python source, thus not exposing real database risks. If actual database interaction were implemented, further security review for potential SQL injection and proper data access control would be necessary. The server itself does not directly consume LLM tokens, acting as an agent.
